Integration of zope.testrunner-style test layers into py.test framework

Project description

The gocept.pytestlayer distribution

Integration of zope.testrunner-style test layers into the py.test framework

This package is compatible with Python versions 2.6 and 2.7. (To run its tests successfully you should use at least Python 2.7.4 because of a bug in earlier Python 2.7 versions.)

Quick start

  • Make sure your test files follow the conventions of py.test’s test discovery

    In particular, a file named tests.py will not be recognised.

  • Add a buildout section to create the py.test runner:

    [buildout]
    parts += pytest
    
    [pytest]
    recipe = zc.recipe.egg
    eggs = gocept.pytestlayer
           pytest
           <YOUR PACKAGE HERE>
    

gocept.pytestlayer registers itself as a py.test plugin. This way, nothing more is needed to run an existing Zope or Plone test suite.

Not supported use cases

  • Inheriting from a base class while changing the layer. See issue #5
  • Mixing classes inheriting unittest.TestCase and a test_suite() function (e. g. to create a DocTestSuite or a DocFileSuite) in a single module (aka file).
    • This is a limitation of the py.test test discovery which ignores the doctests in this case.
    • Solution: Put the classes and test_suite() into different modules.
  • A doctest.DocFileSuite which does not have a layer is silently skipped. Use the built-in doctest abilities of py.test to run those tests.

  • Drop Python 2.6 support.

2.1 (2014-10-22)

  • Update handling of keywords and doctest testnames for py.test-2.5. [wosc]
